"Cristiano Ronaldo has been dismissed from the national team's work after a positive test for Covid-19, so he will not face Sweden. The Portuguese international is well, symptom-free and in isolation", reads a note published on the body's official website.
Ronaldo is the third Portuguese player to be infected with the new coronavirus, after José Fonte and Anthony Lopes, with the three footballers having been removed from the national team stage.
"Following the positive case, the remaining players performed new tests on Tuesday (13 October) morning, all with negative results, and are at the disposal of Fernando Santos for the training in Cidade do Futebol," added the FPF.
Ronaldo's case led to the rescheduling of the last training session before the duel with the Swedes to 5pm (it was initially scheduled for 11am) and also the press conference for the preview of Fernando Santos, which will be at 7pm (it was scheduled for 10.15am).
After four consecutive meetings, with a total of seven goals, the 35-year-old striker will miss the reception to the Scandinavian team, at the José Alvalade Stadium, in Lisbon, in a meeting of the fourth day of Group 3 of the League of Nations.
Portugal and France remain top of Group 3 with seven points, although the Lusitanians have a goal difference, while Croatia are third with three points and Sweden remain bottom with no points.
Portugal-Sweden are scheduled to play at 7.45pm and will be refereed by Serbian Srdjan Jovanovi.
